The new MacOS, Catalina, is finally here — here are the biggest changes in Apple’s big software update for Macs

Apple has officially released Catalina,the next major software update for its MacBook, iMac, and Mac Pro computers.First announced during Apple’s 2019 Worldwide Developers Conference (WWDC), Catalina introduces some big changes to native Mac apps, including the elimination of iTunes and the new ability to control your computer with voice commands.Catalina also features some important updates for iPad owners and developers. A new app called Sidecar will let iPad owners use their tablet as a second screen, complete with Apple Pencil support. New developer tools for Catalina called Project Catalyst will also make it easier for iPad developers to bring their apps directly to MacOS.After more than 18 years, Apple is ready to move on from iTunes. Rather than using iTunes as a catch-all for different types of entertainment, Apple is introducing three separate macOS apps for users to manage their content.A macOS version of Apple Music will become the default app for users to manage their music library, while Apple Podcasts will organize podcast subscriptions. Apple TV will manage downloaded video content and introduce Mac owners to Apple’s streaming TV service.
